The executive meeting of the State Council on February 22 pointed out that the relevant parties should be urged to introduce a number of new measures to speed up the fee reduction. For a time, the "speed increase and fee reduction" was placed in front of us. Unveil the truth about China's broadband network speed and answer all your questions about broadband speed.
With the development of society, the Internet has become increasingly popular in China's urban and rural areas, and the resulting broadband "network speed" has become a very concerned issue for ordinary consumers. At the same time, the Ministry of Industry and Information Technology, the Broadband Development Alliance and some international organizations will also release quarterly data on China's broadband speed, but the data released by the three are often very different, and the measurement standards are not the same.
Great difference in data
In early February of this year, the Broadband Development Alliance released the 14th China Broadband Rate Status Report (fourth quarter of 2016). The report shows that in the fourth quarter of 2016, the average download rate of China's fixed broadband network reached 11.90 Mbps.
Broadband Development Alliance announces our broadband average download data
At the end of 2016, Wen Ke, the director of the Information and Communication Development Department of the Ministry of Industry and Information Technology, responded to questions from netizens who mentioned that as of the end of November, the fixed broadband access rate reached 48 Mbps, which is far higher than the 11.90 released by the Broadband Development Alliance. The value of Mbps.
International organization data is mainly from Akamai, Akamai is the world's largest CDN service provider, it will launch the "Internet Development Report" every quarter, the report covers Internet penetration rate, broadband network speed, mobile network speed, data traffic growth, network Security and many other aspects. The latest report is for the third quarter of 2016. In the report, the average download rate of fixed broadband in China is 5.7 Mbps.
Akamai data shows China's broadband average download rate is 5.7 Mbps
In the report, China's broadband speed is only 85 in the world, far lower than South Korea, Singapore, and even lower than Indonesia and Thailand. The data reported by Akamai is much lower than the data released by the Ministry of Industry and the Broadband Development Alliance.
Test standards are not consistent
Careful readers may have found that, besides the difference in time, the expression of each data is different. The Ministry of Industry and Information Technology uses the broadband access rate, while the Broadband Development Alliance and Akamai use the average download rate. What is the difference between the two?
In July last year, the Ministry of Industry and Information Technology issued a draft of the "Fixed Broadband Access Rate Test Method", which specifies the definition of fixed broadband access rate, that is, from the broadband access point BRAS of the broadband access service provider to the user terminal. The information transmission rate on a segment of access line is generally in kbit/s or Mbit/s.
Generally speaking, the composition of a broadband network is like a highway system. There are highways between cities, municipal roads in cities, and branches and roads connecting users' homes or communities. “Access Line†is like a road connecting your door or community entrance to the municipal road. "Access rate" refers to the rate that the "access line" can reach. It is equivalent to the bandwidth provided by the operator to the user's door. Generally speaking, the higher the access rate, the shorter the waiting time for the Internet, and the better the user feels.
However, the access rate is not the same as the actual download rate of the user. When the user downloads the application using the network, the data transmission rate between the user terminal and the server of the visited website is affected by all links of the entire network, for example, accessing the network at the same time. The number of users, the location of the web server, the bandwidth and processing power of the web server, and so on.
Therefore, the download rate when the user goes online is usually lower than the broadband access rate value. According to the information disclosed by the Ministry of Industry and Information Technology, the actual download rate of broadband users nationwide is generally fluctuating between 50% and 80% compared with the access rate. However, many users said that the measured results are often lower. It is not difficult to understand why the access rate announced by the Ministry of Industry and Information Technology is 48 Mbps, while the average download rate provided by the Broadband Development Alliance is only 11.90 Mbps.
There is another reason why the data provided by Akamai, a foreign institution, is vastly different from that of the Ministry of Industry and Information Technology and the Broadband Development Alliance. Tencent Technology has learned from many inquiries that Akamai does not carry out any business in China, and when it calculates the network speed, it usually opens Facebook, Google and other foreign websites as reference standards to judge China's speed is inevitably biased. .
How to measure your home network speed
Having talked about the data released by so many people, readers are sure to care more about the speed of their homes. Is there any gap between the 50M and 100M that the operators are promoting? Here are a few ways to tell you how to measure the speed of the network.
First, let's first define the relationship between theoretical bandwidth and download speed: If the user is dealing with 20M broadband, 20M here means 20 megabits per second (20Mbit/s), and some real-time speed measurement software used by users usually displays The speed at which the user downloads is measured in kilobytes per second. The relationship between the two is 1:8, so the 20M broadband corresponds to a download speed of 2.5MB per second, and the 10M broadband corresponds to 1.25 per second. MB, 4M broadband corresponds to 512KB per second... and so on.
But these are theoretical rates, and the actual rate tends to be slightly lower than this. Take 20M broadband as an example. If the download speed can reach 2MB/s, it can be basically determined that the network speed is in compliance with the access standard. The measured values ​​fluctuate within the range of 75%-90% of the theoretical data, and can be regarded as normal.
Here are three ways to test the network speed:
Enter the professional speed website
Log in to the professional speed website world network GB/BROADMETER/speedauto, select 10 test points (you can click on the name of the area directly), and then combine the results to determine the speed.
Test with the download tool
Find a popular movie and download it with Thunder, eDonkey and other download tools. Select the high speed download mode in the settings and set the maximum number of connections to 1000. Under normal circumstances, the 2M broadband download speed is 200-280K/S, 4M is 400K-500K/S, and 10M is 1M-1.2M.
Security software speed measurement
You can install Tencent Computer Manager, you can find the "Test Speed" entry in the "Toolbox" and click the "Immediate Speed" button. You can start testing the network speed.
After the method is introduced, the friends can test the speed of the network themselves. If the test results are very different from the data advertised by the operators, then you may encounter fake broadband.
